COMBINATION SQUARE AND BEVEL.

Application filed July 19, 1916, Serial No. 110,145.

To all whom it may concern:

Be it known that I, JOHN DAUJAT, a subject of the King of Great Britain, residing at San Martin, in the county of Santa Clara, and State of California, have invented certain new and useful Improvements in Combination Squares and Bevels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will, enable others skilled in the art to which it appertains to make and use the same.

The invention relates to a combination square and bevel.

The object of the present invention is to improve the construction of carpenters tools and to provide a simple, practical and cilicient device equipped with a plurality of pivoted measuring arms adapted to be arranged to form a square and for marking oil angles and provided also with an extension bevel adapted for measuring braces between studding and the like.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, Within the scope of the claims, may be resorted to withoutdeparting from the spirit or sacrificing any of the, advantages of the invention.

In the drawing Figure 1 is a side elevation partly in section of a carpenters tool constructed in accordance with this invention,

Fig. 2 is an elevation of one of the lon-' gitudinal edges of the tool, the extension bevel being shown in extended position,

Fig. 3 is a view similar to Fig. 2 showing the other longitudinal edge of the tool,

Fig. 4 is a longitudinal sectional view showing one of the arms arranged at an angle to the stock,

Fig. 5 is a longitudinal sectional view illustrating themanner, of mounting the slide of the extension bevel,

Fig. 6 is a detail longitudinal sectional view illustrating the manner of mounting the arm of the square,

Fig. 7 is a transverse sectional view of the device.

Like numerals of reference designate cor- Spccification of Letters Patent.

responding parts in the several figures of the drawing.

In the accompanying drawing in which is illustrated the preferred embodiment of the invention, the combination square and bevel comprises in its construction a stock 1, composed of outer and intermediate longitudinal sect-ions 2, 3 and l consisting of separate strips or pieces secured together by transverse fastening devices and constructed of any suitable material either metal or wood or any substitute for the same. The outer section 2 isprovided in its inner face for the reception of a pivoted arm 6 adapted to fold within the recess and capable also of swinging outwardly against the end wall 7 thereof whereby the arm 6 is supported in an extended position for use. The pin 8 which is provided at its inner end with a suitable head is equipped at its outer end with a nut 9, the end wall 7 is inclined and disposed at an angle of 45 degrees to one of the side edges of the stock 1 and 135 degrees to the other side edge of the stock and it is preferably equipped with graduations 10.

The other outer section 3 is provided at its inner face with a longitudinal recess 11 adapted to receive an arm 12 mounted on a pivot 13 which is equipped at its outer end with a thumb nut 14;. The nuts enable the arms to be clamped in their extended or opposite positions. The inner end 15 of the pivoted graduated arm 6 is rounded as shown and the inner end 16 of the arm 12 is rounded at one corner and is square at the other corner, the end wall 17 of the recess 11 be ing cut away to provide a space or clearance for the square corner of the arm 12 to per mit the latter to fold.

The inner or central section 4 of the stock is provided with a longitudinal recess 18 extending to one end of the stock and receiving a slide 19 consisting of a metallic plate or strip and adapted to permit the same to be extended and to be moved inwardly into it to fold the device. The metallic plate 19 is provided at its outer end with an inclined plate or head 20 set at an angle of 45 degrees to one of the side edges of the stock and adapted to fit against the adjacent end 21 which is beveled to correspond to the inclination of the plate or head of the slide. The slide is provided with a longitudinal slot 22 which receives a projection or pin 23 adapted to limit the outward movement of the slide. The other end 2% of the stock is beveled and arranged in parallelism with the end 21 and the extension slide which constitutes an extension bevel may be of any desired length. In practice the stock will preterably be one foot in length and the slide of sufficient length to extend it say six inches. The extension slide and the inclined head are adapted to vary the efiective length of the device to enable the tool to be employed between studding for measuring and setting braces and the stock and slide may be provided with 'graduations.

The device is equipped with a. spirit level tube '26 to enable the stock to be used as a spirit level and suitablenotches 2'7 and 28 are provided in the stock at the edges thereof to enable the extension slide and the arm to be readily drawn outwardlyior use.

What is claimed is zr 1. A device of the class described including a stock provided with a beveled end and having an opening extending inwardly from the said beveled end said stock being also.

provided with longitudinal recesses opening inwardly from one of the side edges of the stock, said recesses having end walls arranged at different angles to the edge of the stock, a slide mounted in the said opening and having its outer end beveled and provided with an inclined head arranged to fit 7 Copies of this patent may be obtained for five cents each, by addressing the means? against and conform to the configuration of the beveled end of the stock and arms pivoted in the said recesses of the stock and arranged to swing outwardly against the said end walls of the recesses." if

2. A device of the class described including a stock comprising an intermediate and outer longitudinal sections fitting flat against one another, the outer sections being provided at their inner faces with longitudinal recesses open at one of the side edges of the stock and the intermediate section being re- 7 cessed to form a longitudinal opening which extends inwardly from one end of the stock, the latter being beveled thereat, aivoted arms mounted in the recesses of the sides or'outer sections and a slide operating in the said opening of the intermediate section and having its outer endcut at an angle and provided with a plate or head arranged to conform to the configuration of the said bevetcd end of the stock, said slide being movable inwardly and outwardly to form an extension bevel.

In testimony whereof I afiis: my signature in presence of two witnesses.
